基于熵权TOPSIS模型的山东省海岸带生态修复政策效果评价研究

海岸带生态修复政策效果评价是开展海岸带保护修复的重要课题。通过建立海岸带生态修复政策综合评价指标体系，采用熵权TOPSIS模型对山东省2009年至2018年海岸带生态修复政策效果进行综合评价。结果表明，山东省海岸带生态修复政策综合效益呈波动上升趋势。2016年至2018年，政策干预的效果凸显，取得了开展蓝色海湾综合整治、系统推进海岸带生态修复的显著成效。通过分析生态环境和经济社会效益发现，经济社会效益较生态环境效益提升趋势更为明显。同时，本研究发现在扩展生态修复资金的来源渠道、修复效果考核评估方面的政策存在缺陷，提出了促进海岸带生态修复的政策建议，包括坚持陆海统筹、生态优先和建立常态化评估机制。

Evaluation of coastal ecological restoration policy effect based on entropy-weight TOPSIS Model in Shandong province

Evaluation on the policies of coastal ecological restoration is an important issue about coastal protection and restoration. The evaluation indicator framework of coastal ecological restoration policy effect was built to evaluate the effect comprehensively by entropy-weight TOPSIS model from 2009 to 2018 in Shandong province. The results showed that the ecological restoration policy effect in Shandong province fluctuations had been rising on the whole, the effect was promoting from 2016 to 2018 sharply, which reflected the remarkable effect of carrying out the Blue Bay Remediation Action and promoting the ecological restoration systematically. By analyzing the ecological restoration policy effect from the perspective of ecological environment and economic social development respectively, it was found that the overall economic and social benefits was improved faster than the ecological environmental benefits. At the same time, defects were found in expanding the source channels of ecological restoration funds and in assessment and evaluation of restoration effects. In this regard, further policy suggestions were put for promotion of coastal ecological restoration, including insisting on land and sea overall planning, giving priority to ecology and establishing a regular evaluation mechanism.
